Question about installation height for most effective use of carbon monoxide alarms

Q:"How high do I need to install carbon monoxide alarms in my home?" Thanks. Rebecca

Answer: According to information from one of our manufacturers, you can install a CO alarm at any height in your home. The reason is that the molecular weight of air is almost identical to the weight of carbon monoxide. Air is typically composed of 78% nitrogen and 21% oxygen. Nitrogen has a specific weight of 28.013 while carbon monoxide is almost identical 28.011. CO mixes withAir as their weights are approximately the same.

We advise you put the unit high enough that a child cannot tamper with the unit. Also remember that a minimum of 3 carbon monoxide alarms are recommended for a two story home, one on each level near the stairwells. Put one inside each bedroom if you close bedroom doors at night.

We prefer the Costar 9RV, a 9 volt battery powered CO alarm that is for homes or recreational vehicles. These easily mount with two screws. The units cannot be reinstalled on the mounts unless there are batteries installed.

Costar carbon monoxide alarms use a unique sensor that mimics red blood cells. Each sensor takes 28 days to "grow." The sensor reacts with carbon monoxide just as red blood cells do in our bodies. In other words, when a human is exposed to CO, the oxygen in the blood that attaches to red blood cells is replaced gradually by carbon monoxide. When carbon monoxide levels in an area near the sensor reach a level of 70 parts per million in a period of 60 to 240 minutes, the sensor is saturated sufficiently to set off an alarm. Below 35 ppm no alarm will sound. At 150 ppm, the alarm goes off within 10 to 50 minutes. At a level of 400 ppm, the alarm sounds within 4 to 12 minutes. 400 ppm alarm within 4 to 15 minutes.

Safe Home also sells RV carbon monoxide alarms that wire to both 12 volt systems, the coach and the engine, and have a 9 volt battery back-up. The CoStar 12RV-DB 12V RV CO Alarm W/9V Battery Backup protects you even if the 12 volt system is disconnected.

We also sell co alarms by other manufacturers that plug directly into 120VAC outlets. The only problem here is that few outlets are above a child's reach.

Question about life span of carbon monoxide and propane monitor/alarms in RV's and trailers.

Q: "My RV has the original carbon monoxide and propane monitors. When should I replace them? Thanks Tom."

Answer: Safe Home recently learned that all newly manufactured 12V propane alarms and carbon monoxide alarms, whether combination alarms or single alarms, must include an internal shut-down system. The Safe-T-Alert brand we sell has an internal warning system that beeps and flashes when the sensor is dying and then beeps and flashes when the unit shuts down from sensor failure. Typical life is 3 to 5 years unless the sensors are exposed to aerosols such as spray deodorants, cooking sprays, cleaners, etc. Note the date of installation on the outside of the unit with a sticker or log into your owner's manual so you won't be awakened in the middle of no where with the bad news that your units are or have failed.

Below is the information we received from Safe-T-Alert in April 2012 to share with customers.

All Safe-T-Alert Propane and Carbon Monoxide Alarms that are 5 years old and older are beyond their Mandatory Replacement Time and MUST be replaced.

Background: Underwriters’ Laboratories (UL®) Carbon Monoxide Standard UL 2034 and Canadian Standards Association (CSA®) CSA 119.2 now require that all Carbon Monoxide alarms be designed to stop service in 3 to 5 years . UL and CSA have determined that Carbon Monoxide alarms have a limited life. Propane alarms use similar sensors and UL will require the same service life in the near future.

ALL MTI Propane and Carbon Monoxide alarms which are over five (5) years old MUST be replaced. The following Safe-T-Alert Carbon Monoxide Alarm Models MUST be replaced: SA-4, SA-5, 50-541 and 50-542. Models 60-541 and 60-542 over five (5) years old MUST be replaced.The following Safe-T-Alert Propane Alarms Models MUST be replaced: SA-7 and SA-8. Models 30-441,30-442, 40-441 and 40-442 that are over five (5) years old MUST be replaced.

Important! Only install CO and Propane alarms that are UL or CSA listed for Recreational Vehicle Use.

Q: "My CCI propane alarm in my RV has failed. What unit is available as a replacement since CCI Controls is not in business?" Thanks. Ed

Answer: Below is a chart. The entire unit must be replaced if your CCI Controls unit has an automatic gas valve shut off. Safe-T-Alert replacements for that unit will not work with the CCI valve. Note: new standards require that propane alarms shut down 5 years after installed to power. Shelf life is 10 years if not used.

Below is our main replacement chart.

Question about approved carbon monoxide alarms for use in California.

Q: "Do you sell carbon monoxide alarms on the "List of California State Fire Marshal Approved Carbon Monoxide Alarms"? The law now requires these be installed in every single family dwelling. How quickly can they be shipped. Thanks. Steve."

Answer: Yes, we do sell several approved carbon monoxide alarms. Unless you are ordering a large quantity of units, we ship within 3 business days using either the postal service or UPS. The Fire Marshall list expires in July 2012.

Kidde Nighthawk KN-COB-DP-LS Nighthawk Carbon Monoxide Alarm 120Vw/Battery Backup This is a 120VAC carbon monoxide alarm with 9 volt battery back-up.Tamper resist feature unit goes into constant alarm mode if it has been unplugged or has come loose from the outlet.7-Year end of life warning alerts user to replace CO alarm after 7-years of operation (40% longer than other CO alarms).

If there are other approved Kidde units you would like pricing on, please let us know. We are able to discount larger quantities of these products. Most come in case of 12 or 24 units. Remember you need to install at least one carbon monoxide alarm on each level of your home and one CO alarm in every bedroom where the door is shut at night. Do remember that if you have gas burning appliances like ranges, stoves and furnaces that you also should add gas alarms for propane or natural gas to protect against explosions and fires.

Q: "Which carbon monoxide alarm would you recommend for use in a truck sleep compartment? I manage a large trucking company and am concerned about carbon monoxide leaking into the sleeper compartments.We have now begun installing auxilliary power units so the truck can be heated and cooled when the driver is sleeping. Thanks. Thomas."

This is from our customer, dated today, May 22, 2011. "We had an incident several years ago that involved a driver being overcome by Carbon Monoxide in the sleeper of a truck that required medical treatment. It was traced back to an exhaust leak under the cab. Our safety committee reviewed the incident and decided we should look in to installing CO alarms in the sleeping compartments of the trucks. I did research on several types and choice to use the model/style you offer. Also within the last couple of years we have been installing A.P.U.'s (auxiliary power units) on our trucks. They are used in place of the chassis engine running while cooling and heating the truck when the driver is sleeping. This little internal combustion engine produces CO, and is located lower than the sleeper, so it is an extra safety tool while using those small engines. I hope this gives you a little information on why and where we use them."

I hope this helps with your decision. Carbon monoxide is a silent killer that, if it does not kill, can cause permanent brain damage.
